    i have tried this fix and it does not seem to be working for us. We followed the instructions and the spa seems to heat up ok for a while but it is cutting off (ie red to green light) when the spa is a lot colder than 40C - maybe it is a thermostat problem???
    any help would be v greatful.
    thanks

Same problem I had so I seperated the globe by taking out the 5 screws around the middle then removed the nut from the hole the filter sits on its a strange fitting and must have a special key but I improvised by tapping it anticlockwise using a screwdriver and rubber mallet, once open identify the heater unit (it has a single wire going into it and is fastened to a length of metal pipe) and remove it by loosening the clamps at either side and pull the heater free, once free dismantle the plastic casing on the top of the heater inside you will see the live, neutral and earth wires, you can see the live (brown) wire goes to the water flow switch then the temp switch then the heater all I did was bypass the water flow switch by disconnecting the short wire from it going to the heat sensor and replacing it with the brown wire coming from the mains and it works fine now

We had our lay z spa just over 12 months and then the heater stoped working. I found a very good repair guide on ebay and was able to fix mine. Very happy now. Seems like a lot of people have issues.

HI

this worked for me too! getting centre nut off was easy using thin pliers - have taken some photos along the way - i'll see if I can get them up here

    The 1st picture is of insides after top has come off - you need to remove the white plastic attachments. They are connected with two brackets which split in half when you remove the screws - mine also had some infexible sealant around which I had to cut off - and then used new silcone when replacing.



    The second picture is the top of the air blower unit - I had to remove this to get at one of the plastic brackets.



    Picture 4 shows the brackets half off - don't drop the little screws! You'll also find a rubber washer under each of the tubes - these need to be reseated correctly.



    Next picture - heater element withdrawn form tube - it's like akettel element - next job remove the plastic cover. Sorry this shot is a bit blurry

    - you can see the brown live power wire coming in from the left going to the flow switch far right - there's a short brown lead that takes the power to the element in the centre.

    Next shot shows how wires look afterwards - note no wires on flow switch as small wire has been discarded, and the brown wire from the mains goes to the terminal on the heater element that the short brown wire used to attach to.



    I took off the plastic cover underneath the element wiring to have a look at the flow switch - it works by water pressure pushing a rubber piston inside the switch to turn on the power - mine was fouled with deposits - I priced one up - you can get them for around £37.



    the above fix works, but as precaution I don't run the heater when anyone is the pool in case of leaks - good luck!

    Ya, I had E06 whenever I turned on the heater. pulled the cover, disconnected the sensor on the outside of the heater, put it all back together, and bingo, we have hot tub again! This works! (may cause tub to burst into flames, use at your own risk)

In reponse to gallydavid, I had the same problem, what everyone says is pretty much correct. It is probably a bit dangerous to bypass the pressure switch inside the heating unit but it is easily done. (on your head be it!) Once you have dismantled the pump/blower unit and found the heating tube, remove the small screws that cover the wires going into the element. Look at the brown wire (live) it goes first to the pressure switch. disconnect both wires from the pressure switch. Next disconnect the brown wire that went from the high heat cut out (a small disc shaped object attached to the element)to the pressure switch. this wire will be about 50-75mm's long. Discard that wire. Now connect the brown wire that was on the pressure switch that goes to the control unit to the high heat cut out. this means you have removed the pressure switch from the circuit. put everything back together.
NOW MAKE SURE YOUR SPA IS FULL OF WATER AND WATER HAS FILLED THE FILTER VESSEL, i.e you have bled the filter, then turn on the heating.
It should now work.

    Just fixed mine, the pressure switch just unscrews, take it out use a paper clip to remove the dirt etc. from the hole push on the diaphragm until the micro switch clicks blow into the switch to check it works, you will hear the switch clicking, screw it back in and connect wires.

Thank you for the great info . It's great having my hot tub back. I did take a shortcut. Instead of breaking the clamps on the heating element and needing to reseal them, I removed 2 screws from the base of the heating tube where it meets the main body as well as 4 screws from the base of the pump where they all fasten to the main body. This allowed me to lift the unit enough to get the cover off of the flow pressure switch and do your modifications without any silicone or breaking any seals. Thanks again everyone

    ive also done this conversion and now the filtering circuit doesnt work and when i set the temperature the previous night to 24 it still said 24 the next day disconnecting that pressure switch must do something to stop the circulation circuit to kick in has there is no pump noise when the filter circuit is activated.

THANK YOU SHANDYT. The inspired solution proposed by Shandyt has worked for me and I thank him for it. It saves anguish and £200 GBP. For those who undertake the job, be careful to learn how the two interior plastic pipe seals fit and screw shut again as they are a bit tricky and I found it necessary to take them off to give access to the fittings. Otherwise its a doddle! Clearly the flow switch is the weak point on these spa heater/pumps and Bestway must surely know this, so one suspects there may be built-in obsolescence in an otherwise solid product. Grateful Fred

I have just spent four hours on my unit. In my unit though, the pressure swith wires are white, one with red markings on them. The temp sensors have black wires to them. These all run into a motherboard separatly. I straight out cut the pressure sensors wires, no luck. I joined the cut wires together, no luck. Put it all back together the way it was built and no luck. Any guide on what wires to cut and join on these newer units with the different coloured wiring? Tony

Lay z spa pump control panel condensation / steamed up.

The buttons on my spa had stopped working although it still powered up ok. There was water showing in the display.

I opened up the "egg" to find I couldn't get at the back of the panel as it is sealed.

I used a hair dryer to heat up the panel from inside the unit (blowing air from a distance into the hole where the wire goes into the panel). I alternated this with heating from the front of the panel to clear the steam. Eventually the steam cleared and stopped forming on the screen.

I put the unit back together and it worked first time.

Be careful not to over heat the unit.

Why doesnt my leisure bay spa get hot


This could be caused by a couple things. In order for your spa to heat your pump must be working, your heater and heater sensors must be good. If your heater is bad usually the breaker will trip. If that's not happening read below...
Does water shoot out of the jets when you press the jets 1 button? If not then you have a bad pump or the pump is air locked. The heater can't turn on if the pump does not push water through the heater. You'll know if this is happening because you'll get an error code on your control pad.
So your jets are working but no heat. This is the most common problem. Your spa has a sensor that tells the spa if it's ok to turn the heater on. That sensor is prone to failure so everything can be fine but the heater will not turn on. Get the model number off your spa pack and click the link below. Call and tell them you need a pressure switch and give them the model number. Install the new switch and you're back in action.

Hot tub heating is working but pump has stopped


you may have a system that uses a small circulating pump that circulates the water thru the heater to keep water temp at proper level (this is usually the case with hot springs spas and is because it is the most cost effective way to maintain constant water heat without using a full size pump or two speed pump just to push water past the heater core. therefore the issue is you have a problem with your jet pump and it has nothing to do with the circulating and heating portion of the spa. you can check to see if there are any reset buttons in or near the equipment as well as open enclosures to make sure everything is clean and dry also make use any contacts on spa skirting are secured propertly

Layz spa keeps going off says on readout 6cf.heater is fine pump everything else is ok cheers kevin


You have a problem with the RCD (residual-current device). This is the part of the plug that you have to push reset on before a current will flow. You can repair this by buying a new RCD plug and rewiring it or if you already have an RCD socket adaptor for another appliance, you can just cut of the plug on the pod/ pump and rewire it into a rubber plug and then plug this into the RCD adaptor and the lay z spa should no longer cut out. The RCD is important because you do not want to blow the unit inside.
I hope this helps, If you need more assistance, please ask.

Check the pump make sure that it is getting power. If there is power to the pump and nothing is working then pump is bad. Also this could be your computer board is bad, a inline fuse. or the Jandy is bad
